The USA Green Card Lottery program from USA Diversity Lottery helps non American citizens qualify for immigration to the United States. The Diversity Lottery produces and assigns 55000 immigrant visas on a yearly basis from the results of a lottery system, to people living in countries that have a low rate of immigration to the United States. These prospective immigrants then have a great opportunity to obtain a green card and to legally receive the right to live, work and study in the USA.
